C.N.C. machined from billet aluminum.
Stiffer spring to allow for more consistent boost pressure
Successfully tested and used on stock unmodified 996TT cars up to heavily modified +1000 HP cars. Available in silver or black. A great upgrade that everyone will eventually have to do on a maintenance basis anyway.
ALL THE BEST
